* fix: CONFIG_NETCONSOLE start/handle this stuff only outside SPLHannes Petermaier2014-06-19-2/+2
| | | | | | | SPL stage does not support various networking things, and therefore CONFIG_NETCONSOLE cannot be built within SPL. Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at>
* net: rename and refactor eth_rand_ethaddr() functionMasahiro Yamada2014-05-12-22/+0
| | | | | | | | | | | | | | | | | | | | Some functions in include/net.h are ported from include/linux/etherdevice.h of Linux Kernel. For ex. is_zero_ether_addr() is_multicast_ether_addr() is_broadcast_ether_addr() is_valid_ether_addr(); So, we should use the same function name as that of Linux Kernel, eth_rand_addr(), for consistency. Besides, eth_rand_addr() has been implemented as an inline function. So it should not be surrounded by #ifdef CONFIG_RANDOM_MACADDR.

* lib: uuid: code refactor for proper maintain between uuid bin and stringPrzemyslaw Marczak2014-04-02-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Changes in lib/uuid.c to: - uuid_str_to_bin() - uuid_bin_to_str() New parameter is added to specify input/output string format in listed functions This change allows easy recognize which UUID type is or should be stored in given string array. Binary data of UUID and GUID is always stored in big endian, only string representations are different as follows. String byte: 0 36 String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx string UUID: be be be be be string GUID: le le le be be This patch also updates functions calls and declarations in a whole code.

* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

* net: execute "miiphy_init" if CONFIG_PHYLIB definedAlexey Brodkin2014-02-07-1/+1
| | | | | | | | | | | | | | | | | | | | In "common/Makefile" "miiphyutil.o" gets built if any of the following items enabled: * CONFIG_PHYLIB * CONFIG_MII * CONFIG_CMD_MII So it's possible to not define CONFIG_MII or CONFIG_CMD_MII and still use functions like "miiphy_get_dev_by_name". In its turn "miiphy_get_dev_by_name" traverses "mii_devs" list which is not initialized because "miiphy_init" never got called.

* net: nfs: add dynamic wait periodMatthias Brugger2013-06-24-21/+53
| | | | | | | | | | | | | | | This patch tackles the time out problem which leads to break the boot process, when loading file over nfs. The patch does two things. First of all, we just ignore messages that arrive with a rpc_id smaller then the client id. We just interpret this messages as answers to formaly timed out messages. Second, when a time out occurs we double the time to wait, so that we do not stress the server resending the last message.

* NET: Fix system hanging if NET device is not installedJim Lin2013-06-19-1/+2
| | | | | | | | | | | | | If we try to boot from NET device, NetInitLoop in net.c will be invoked. If NET device is not installed, eth_get_dev() function will return eth_current value, which is NULL. When NetInitLoop is called, "eth_get_dev->enetaddr" will access restricted memory area and therefore cause hanging.

| * OMAP: networking support for SPLIlya Yanok2012-10-01-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.

Without this patch u-boot displays the warning: *** Unhandled DHCP Option in OFFER/ACK: 28 The patch suppresses the warning and ignores DHCP Option 28.

* net: Improve the speed of netconsoleJoe Hershberger2012-09-24-12/+22
| | | | | | | | | | | | | | | | | | | Previously u-boot would initialize the network interface for every network operation and then shut it down again. This makes sense for most operations where the network in not known to be needed soon after the operation is complete. In the case of netconsole, it will use the network for every interaction with the shell or every printf. This means that the network is being reinitialized very often. On many devices, this intialization is very slow. This patch checks for consecutive netconsole actions and leaves the ethernet hardware initialized between them. It will still behave the same old way for all other network operations and any time another network operation happens between netconsole operations.

| | | | | | | | | | | | | | | | | | Cisco's arp-proxy feature fails to ignore the link-local address range This means that a link-local device on a network with this Cisco equipment will reply to ARP requests for our device (in addition to our reply). If we happen to reply first, the requester's ARP table will be populated with our MAC address, and one packet will be sent to us... shortly following this, the requester will get an ARP reply from the Cisco equipment telling the requester to send packets their way instead of to our device from now on. This work-around detects this link-local condition and will delay replying to the ARP request for 5ms so that the first packet is sent to the Cisco equipment and all following packets are sent to our device.
